This instructable is for keeps our swimming pool water safe and clean, chlorine eliminates most dangerous contaminants. You need only a plastic bottle, chlorine tablets and some tool for make several holes in bottle body.

Step 1: Materials

Just a few components
- Bottle
- knife
- Drill
- Chlorine Tablets
- Swimming Pool (Off Course)
A great solution for this problem. Thank you, you saved me a lot of money and gave me some fun hobby time back :D
Easy. Thanks!
And, if you really wanted to, you could decorate the bottle to make it look a bit pretty, like glue a fake duck on top.
simple, cheap, works good and its just awesome. fabulous
I would never put chlorine tablets in my toilet tank again. Even in a large pill bottle with the smallest holes drilled in it, still ate any rubber seals and metal in the internals within a matter of weeks. (The bowl was, however, the cleanest it's ever been LOL).
Upps !!!!!
GREAT IDEA................now to wait for Memorial Day. Right now the pool is under 3 feet of snow and ice!
That is an interesting idea. Do you think that you could make a small one out of a 20 oz soda bottle and use it in the toilet tank. This might keep the toilet clean and using the cheaper pool chlorine tablets than the expensive toilet chlorine tablets?
